After your adding your modification, im having back response from the wiz811 module, but there is somothing wrong, i can’t setup properly the GWR,SUBR,SHAR and SIPR registers.
Here s a screenshoot of my logic analyzer.

There is a problem in my /RESET line, and in the logical level of MISO,MOSI,SS,SCK.

For the issue with the /RESET line i have put a 10k resistor, and for the logical level issue, y made a logical converter 3V3 to 5v ,5V to 3V3 with four 2N7000 and a few resistors.
In the Wiz5100 Datasheet says that the IC is 5V tolerant, but in my case doesn’t work without adapt the levels.
